Great Scene, great model, love the expression
As it is finished project, consider my C&C niggling =)
For all the nodes you used I find the compositing and postpro not too good though. blurry and oversaturated for my taste.
And the clouds really suffer from the jpeg compression which personally really distrubs me and makes me focus on that instead enjoying the image
And I am annoyed by the lens flare ^^ since the beginning of photography and moviemaking camera men try to avoid lens flare, and yet it seems everyone puts them in his image. Why add a photorealistc element which is considered bad to an image thats obviously a toon image?
And I would have loved the horse to have a more heroic chest.
However the face and expression is grand. A character with character
